DENVER -- Reigning Olympic downhill champion Lindsey Vonn has crashed while training ahead of her return to racing following major knee surgery.
U.S. Ski Team spokesman Tom Kelly says Tuesday that Vonn is being evaluated at a hospital after being taken off the slope at Copper Mountain, Colo., on a sled.
Kelly says he is not sure whether Vonn hurt her surgically repaired right knee.
He adds: "We have no reason to believe it's anything significant right now."
The four-time overall World Cup champion tore her ACL and MCL in a crash at the world championships in February. She has been aiming to return to Word Cup competition next week in Beaver Creek, Colo.
The Sochi Games are in February.
